In order...at least as much as I can think of. Stop if any step
solves your problem.

Are you using any cable extenders or after market video cables? If so
try without them or with a different cable. If not go to next step.

Try removing and reseating the video cable (turn the computer and
monitor off first).

Try resetting the monitor to it's default state (you'd have to read
the manual for that)

Try removing and re-seating the video card (turn the computer off to
try that)

Try running the monitor at a different resolution (and/or a different
refresh rate.)

The voltage dividers for the tube's grid power are going bad. You can
adjust them yourself with a small plastic screwdriver if you don't mind
risking electrocution. They're on the high voltage flyback transformer;
the thing with a red cable going to the tube. The adjustment has to be
done with the monitor on so don't bump into anything. You'll see two
plastic screws. One, possibly labled "grid," makes the monitor brighter
or dimmer - don't change that one! The other is the focus.

Some computer monitors have secret on-screen calibrations that can
adjust the focus over a small range. Google for your model number and
"service mode".

Are you sure the video adapter card is OK? A low-end video card may not
have the bandwith necessary to support high refresh rates at high
resolution. Just because the card will *generate* a given mode doesn't mean
that it will work well. Try the following steps.

1. Reduce the refresh rate to 60 Hz The monitor may seem to flicker a
little, but don't worry about it.

2. If there was no change, the problem is likely in the monitor

3. If that improved the resolution, then try removing any monitor extender
cables and play with higher refresh rates again. If that fixes the probem,
great, otherwise

3. Replace the videa adapter card with a better one.

You ever see the commercial where the little boy asked his dad what dial up
was like? Remember what his dad did with the Monitor! I have had similar
situations with computer monitors.

Finally found one that seems to be holding up.

Sorry you are having problems with your monitor. I hope you get them worked
out.

I would like to throw one out the window just once it must feel great!

I know this is two years later, but if anyone else is having trouble with a trinitron monitor becoming blurry, here's a couple tricks. First, unplug the monitor with it on. Next, blow out the insides with an air can. Try this first. Mine would become blurry intermittently and this has fixed it so far.

I want to thank you "Kevin McMurtrie" you have made my day!
I was checking message boards and googling (my monitor is very blurry)
Your Answer Was The Very HELP I Needed.......You are A Hero..Couldn't afford to buy a new monitor, and I was just ready to throw this Dell Monitor In The Trash!!!!

Thank You, Kevin McMurtrie

I also wanted to say thank you "Kevin McMurtrie"! You have made my day as well! Even years later your solution is still valid ;-)

My Dell P992 CRT monitor (7 years old) went also very blurry (after going blurry intermittently) yesterday. I also found the service manual online, which indicated where the focus screws were located (this monitor has 2 focus screws). Adjusting them made it focused again! It was a bit scary to have the monitor on and open at the same time, but using a plastic screwdriver (made out of a plastic fork it went without problems!

Thanks again! Saves me from throwing away my monitor

Cheers!

I have the same issue with my Dell. I have 2 Trinitrons. One is working fine, but the other has intermittent blurriness punctuated by a metallic-sounding 'ping' sound. In addition, there are slightly diagonal thin white lines running across the monitor.
I was getting the pinging sound before without the blurriness, but now the blurriness has been added.
I"m guessing it's just going bad, soon to be a doorstop?
I'll work through your suggestions (short of playing inside with a screwdriver - don't do this at home, kids...) and see if anything helps.
I have a lot of equipment hooked up here. And one of the monitors is hooked up via a shaky adapter and a KVM switch, but I'll have to check the configuration to see which one. It seems to me that with the monitors side by side, if interference was the issue, it would be happening with both?
Thanks again.

EDIT - It just made the loudest 'pop' sound I have heard it make. The display moved momentarily, then the blurriness went away.
